Finally pulled the trusty old Panasonic battery out of my CX-5 and replaced it with an Optima Yellowtop. When I buttoned everything up, I still had my radio stations and settings right where I left them.
Buy a nice battery. I bought used 6 months ago and did a week of nightly research first, by FAR the biggest complaint was the battery going out or having constant low messages. I put a yellow top in mine a few days after getting it, not one issue this far.
Nice hack. I have a Yuasa that will be 13 years old this year and still going.
I have an Optima Red Top battery in my 2006 Dodge Magnum that's at least 5 years old (probably older). It was heavily abused for years. Since then, this battery has been in my daily driver (5.7L V8), and it's still cranking strong with no issues.
I put an Optima Red Top in it when my tester showed it below 75% health, about a year ago.
IMO, the Optima Yellow top is your only option. It will last 5-10 Years.
My wrx would be parked for long periods and I had optima yellow tops. I liked how hard it cranked, good for e85 cold starts. But wow, after the second one went flat I stop getting them. Bought some random battery and it\u2019s been holding charge no problem.
Optima batteries are absolute trash for deep discharge use. Their quality is also not what it used to be. Anytime I see them in marine use, I swap them out for a proper AGM. Only thing they are decent at is starting applications in cars.
I bought a red top.. in like 3 weeks it wasn't taking a charge and it got returned. Never again
From my experiance with the optimal batteries you are better off with a Walmart battery and save money. I tried the optimal 2x. Both failed within a year. They were warranties but the replacements didn't last much longer.
